ILSBMR: improved LSBMR (ILSBMR) method

The Least Significant Bit Matching Revisited (LSBMR) is among the most commonly used methods on image steganography, aiming to make only smaller changes in an image. While security is considered as one of the basic evaluation criteria for steganography techniques and notably, LSBMR can be easily recognized due to its well-known structure, it is important to find a way to help improve this approach so that it might cause less variation in the image and also increase security. To this end, the current paper deploys divided blocks of the original cover image and a selection of the best layout to embed secret message bits from each block into color images by using LSBMR. The simulation results indicate that this improved method makes small changes in the image and increases its security, compared to the LSBMR technique.
